Abstract

PROBLEM TO BE SOLVED: To eliminate the trouble in selecting a melody by automatically selecting melodies on the basis of caloric consumption by singing, and also realize not all random but leaving selection. SOLUTION: A caloric amount consumed by singing each KARAOKE music is pre-stored in an index table, and when a singer inputs a caloric amount, one or plural pieces of KARAOKE music consuming the caloric amount are selected and played. In a single melody selection mode, plural pieces of KARAOKE music each of which consumes the same amount of calories as inputted are selected and the singer is made to select one of them. In a plural melody selection mode, plural pieces of KARAOKE melodies, of which the total caloric consumption becomes as much as the input caloric amount, are selected and they are played in a prescribed order.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke apparatus for performing automatic music selection based on the amount of calories.

[0002]

2. Description of the Related Art A music selection operation in a general karaoke apparatus is to check a music number of a desired music by a table of contents in which music names and music numbers are associated with each other, and to input the music number to a main body of the apparatus from a remote controller. Was. There has also been proposed a method of selecting and playing music at random.

On the other hand, a karaoke apparatus having a function of displaying the amount of calories consumed by singing a karaoke song has been proposed.

[0004]

In the above-mentioned general song selection method, it is troublesome to consider the song to be sung by himself and search for the song number in the table of contents. There is a problem that it is difficult to find whether to search for. In addition, the conventional random song selection function is a function that simply selects a plurality of songs at random without considering the requirements of the singer such as singer's preference at all, so the singer's familiarity with the selected songs springs up It was difficult and interesting.

[0005] It is an object of the present invention to provide a karaoke apparatus which solves the above-mentioned problems by performing automatic music selection with calories to be consumed.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a storage means for storing a plurality of music data for playing a karaoke song and for storing a calorie consumption when singing each karaoke song; It is characterized by comprising input means for inputting, and music selecting means for selecting a karaoke tune having a calorie consumption amount substantially equal to the input calorie amount.

[0007] The calorie consumption stored in the storage means is:
The amount of calories that a singer would consume when singing the song normally. When the singer inputs the calorie amount, a karaoke tune having a calorie consumption almost equal to the calorie amount is selected. The term “substantially the same” refers to, for example, a range where the error between the input calorie amount and the consumed calorie amount is up to about 10%. Also, a rough index calorie amount may be separately stored for song selection separately from the actual calorie consumption amount. For example, if the calorie consumption is 517
In the case of calories, rough index calorie amount is 5
If the data is stored in 00 calories and the input for selecting a song is accepted as a rough numerical value such as 500 calories, the music can be easily selected by judging the coincidence between the input value and the amount of index calories. That is, in this case, 450-
Since the range of 549 calories is indexed as 500 calories, the rough range can be said to indicate the range to which the calorie consumption belongs. That is, the storage means may store a range to which the calorie consumption belongs, and the input means may be a means for inputting the range to which the calorie belongs.

Further, the present invention provides a storage means for storing a plurality of music data for playing a karaoke song and for storing the amount of calorie consumed when singing each karaoke song, and an input for inputting a total calorie amount. Means, and music selecting means for selecting a plurality of karaoke songs so that the total amount of consumed calories is substantially equal to the inputted total calories.

The input total calorie amount is sufficiently larger than the calorie consumption amount of one song, and the total calorie amount of a plurality of karaoke songs is the total calorie amount.
The music selection means selects a plurality of music pieces so that the total becomes the total calorie amount. In this case, the genre of the song may be specified. Thereby, a plurality of songs can be selected only by inputting the total calorie amount.

Further, in the present invention, the music selection means arranges the music order of the plurality of karaoke music so that the change in the calorie consumption for each music becomes a predetermined curve. That is, first play a light song with low calorie consumption and gradually play a heavy song with high calorie consumption, or conversely, play a heavy song with high calorie consumption first and gradually reduce calorie consumption. By arranging, for example, a small number of light songs, the singer can easily sing.

According to the present invention, a storage means for storing a plurality of music data for performing a karaoke music piece, an input means for inputting an identification code of a singer, and a plurality of karaoke music pieces are selected according to the input of the identification code. And control means for notifying the singer of the identification code when playing the selected karaoke song.

According to the present invention, a plurality of karaoke songs are automatically selected without the singer performing individual song selection operations. Since the singer does not know which song has been selected, the singer notifies the singer using the identification code of the singer when performing the selected karaoke song. As described above, by automatically selecting a song on behalf of a singer, the singer can be released from the song selection operation, and a new song having a different taste can be sung. Also, in this case, if the vocal data is attached to the karaoke song and the singer cannot automatically sing, the vocal is automatically output.
Even if an unknown song is selected, only the karaoke performance is performed without any nuisance, and the singer can also practice singing the vocal output. In addition, the range of automatic song selection may be performed from all songs, but by limiting the song genre or the like, the possibility of selecting songs that the singer does not know at all is reduced.

I have. Each event data is described in MIDI format. The sequence program counts timing data at a predetermined tempo clock, and when the count data is counted up, reads out event data following the count data and outputs it to a predetermined processing unit. The timing data may be described by the time from the beginning of the song or by the interval from the immediately preceding event. Since the event data of the music track is data for generating a music sound,
It can be described in a general MIDI format.
The other data is not a normal MIDI message, but this track is also described in a MIDI format as a system exclusive message in order to unify the implementation and facilitate the work process.

FIG. 2B is a diagram showing the structure of the index table. The index table is a table for searching music data corresponding to a user's music selection input. In this index table, data of index calories, song numbers, genres, genders, song names, and actual calorie consumptions are stored for each karaoke song. The actual calorie consumption is the calorie that would be consumed when the singer sang this song. In addition, this numerical value is displayed in the calorie of the physical unit,
500 calories is 0.5 calories when represented by Cal (large calories) which is a unit of calorie of food. The index calorie is a calorie amount that is used as a guide when music is selected by the calorie music selection function. That is, a karaoke song whose actual calorie consumption is in the range of 450 calories to 549 calories is given an index calorie of 500 calories. The song number is an identification code for identifying the karaoke song. Genres are enka, pops, animation,
It is classified as a new song.

The single music selection function as the first calorie music selection function will be described. The user inputs the calorie amount.
The input calorie amount is 100 calorie units (10
0, 200, 300,...). The karaoke apparatus searches the index table for karaoke songs whose index calories match the input calorie amount, and displays a list of the song names. The user selects one of the songs.

Next, a description will be given of a multi-tune selection function, which is a second calorie selection function. The user enters the total caloric content. This total calorie amount is sufficiently larger than the calorie amount consumed in one song (the genre may be specified at the same time). Then, the karaoke apparatus selects a plurality of karaoke songs so that the total of the index calories becomes the inputted total calories,
This is registered in the reserved music list and played sequentially.

When a plurality of songs are selected by the multiple song selection function, if the plurality of songs are continuously played, the same singer will sing continuously, and the requested song of another singer will be added to the reserved song list. Register with. And since the singer does not know which song was selected by the multiple song selection function,
The tune selected by the multi-tune selection function is notified that the tune is the tune and who has selected the tune. For example, a symbol (icon) for each user who performed a multi-track selection operation
Is determined at the time of the music selection operation, and this is displayed together with the music title at the time of starting the music.

FIG. 4C is a diagram showing a reserved music list. In this list, up to ten requested song numbers can be registered. In addition to storing the icon of the singer who selected the song in correspondence with the selected song number, and in the case of a song selected by the calorie selection function, the song order of the song, that is, the song number of all songs Whether there is (n / m) is stored.

FIGS. 3 to 5 are flowcharts showing the operation of the karaoke apparatus, and FIG. 6 is a view showing a display example of a monitor of the karaoke apparatus. FIG. 3 is a flowchart showing the operation in the single song selection mode in which the single song selection function is executed. The operation of the single song selection function and the multiple song selection function described with reference to FIG. 4 are realized by a script executed by the karaoke apparatus. It is performed by selecting with.

In the single song selection mode, the user operates the remote controller 8 to input a calorie amount (step 1).
01: hereinafter simply referred to as 101). 100 calories
The input is made in units of calories. In the case of 500 calories, "5" is input. Alternatively, as shown in FIG. 6A, a plurality of foods (ramen, rice balls, dango) may be displayed, and the singer may select one of them. Then, the calorie amount of the selected food is set as the input calorie amount.

When the calorie amount is input, a karaoke tune corresponding to the input calorie amount is searched from the index table (102), and the searched tune names and tune numbers are displayed in a list on the monitor 6 (103: FIG. 6 (B)).
The user selects one of the songs (104). When one song is selected, the song number of that song is registered in the reservation list (105). At this time, since the single song selection mode is set, the song order storage area indicates that the first song in the song is “1/1 /
1 "is stored.

Thereafter, when the order of the music comes, the music data is read out and played. Then, when the performance of this song is completed (106), the actual calorie consumption stored in the index table is displayed (107).

FIG. 4 is a flowchart showing the operation in the single song selection mode in which the multiple song selection function of selecting a plurality of songs by the total calorie amount is executed. In the multi-tune selection mode, the user operates the remote controller 8 to input a calorie amount (111). The method of inputting the calorie amount may be the same as in the single song selection mode. Next, the user selects the genre (112), the calorie consumption curve (113), and the icon (114) of the song. The genres of the songs are classified into enka, pops, animation, new songs, and the like as described above.
The calorie consumption curve is a curve obtained by graphing the calorie consumption of each song when a plurality of songs selected as shown in FIG. 7 are arranged, and as shown in FIG. , And a down type curve as shown in FIG. 3C. The icon is a figure as shown in FIG. 6 (C), and the selected icon represents the user who has selected the multiple songs. The user ID of the user may be used instead of the icon.

When the above information is input, the total calories,
The index table is searched based on the genre, and a plurality of songs whose total number of index calories is the total calorie amount is selected from songs of the designated genre (115).
Then, the song order of the plurality of songs is edited so as to become the selected calorie consumption curve (116), and a list is displayed on the monitor 6 (117). And these songs are user ID,
The music is registered in the reserved music list together with the music order (118).

In the multiple song selection mode, a plurality of songs are selected at a time, so if these songs are registered in the reserved song list at once, the same person will sing a number of songs continuously. Therefore, in step 118, as shown in FIG. 2C, a plurality of selected songs are registered every other song, and the requested songs of other users are registered in the blank order. Good. If the number of selected songs cannot be registered in the reserved song list, the song names and song numbers of the songs that could not be reserved are stored in another storage area, and the performance proceeds, and the reserved song list is left blank. When the music is completed, the remaining songs may be registered.

FIG. 5 is a flowchart showing the performance processing operation of the music registered in the reserved music. When the previously played song ends, the first song number in the reserved song list is read out (121), and performance preparation for that song is executed (12).
2). If the head of the reserved song list is blank, the song number in the next column is read. The preparation of the performance of the music includes an operation of reading the music data of the music number from the hard disk or the DVD into the RAM, an operation of initializing the sound source so as to form a musical sound of the music, and the like. At this time, it is determined whether the song is a reservation with an ID such as an icon that can identify the singer (123), and if the song is with an ID, it is determined whether the ID is the same as the ID of the song played immediately before. (12
4). If the IDs are the same, the start of the performance is delayed for a predetermined time in order to break the singer (125), and then the performance is started. At the time of this delay, a message as shown in FIG. In the case of a reserved song with an ID, an ID is displayed together with the song name at the start of the performance to indicate who is to sing (126:
FIG. 6 (E).

Thereafter, the performance is started (127), and voice analysis data obtained by analyzing the voice input in accordance with the performance is input (128). This voice analysis is performed by the voice signal processing device 3, and information such as the pitch and volume of the singing voice is input as voice analysis data. The singing is scored by comparing the voice analysis data with the guide melody data in the performance data (129). When it is determined from the input voice analysis data that the singer has not sung at all, the reproduction of the guide vocal is automatically turned on (130, 132). In this embodiment, in the case of a calorie selection mode in which the singer selects a song without directly specifying a song name, a song unknown to the singer may be selected. Guide vocals are turned on. If there is an input voice, the guide vocal is not turned on even if the pitch is slightly shifted (131). Step 12 until the song ends
Repeat the operation of 8 and below.

When the music is completed (133), the score is displayed (134), and it is determined whether the score is equal to or more than a predetermined score (135). If the score is equal to or higher than the predetermined score, it is determined that the song has been sung correctly and the calorie of this song has been consumed (136), and the actual calorie amount of this song is read out from the index table and displayed (137), and the multiple song selection is performed. In the case of the music in the mode (138), the actual calorie consumption is added to the total calorie consumption storage area (139), a display as shown in FIG. 6F is performed, and the operation is terminated (140). .

In the above operation, whether or not the calorie of the played karaoke song has been consumed is determined based on the scoring result.
Although the determination is made based on / 0, the consumption may be calculated by determining that the ratio according to the score has been consumed.

In the calorie selection function, a calorie input may be input directly from a button switch for calorie input provided on a remote controller.

Further, the index table may not be provided with an index calorie column, and a karaoke tune having a small error between the input calorie amount and the actual calorie consumption amount may be selected.

The calorie selection function may be realized as a music selection device dedicated to music selection separately from the karaoke device.
In this case, the music selection device includes a device for inputting a music selection result to the karaoke device main body like a remote control device.

[0049]

As described above, according to the present invention, a karaoke song can be selected only by inputting the calorie amount or the identification code. Music selection becomes possible.
